Uprev tunes your QR25

[uprev]

Hey guys just wanted to let you know we've done a few of the QR25 motors now. Sentras and Frontiers. We even have cam adjustment available in our software. We have a few customers with forced induction QR25 builds going right now and we have no issues supporting your forced induction tuning needs.

Looks like the Sentra is 2004 and newer that uses the newer Nissan ECU that works with our software. The Frontier/Xterra is obviously 2005 and newer. Not yet certain which year they moved the Altima to the newer style ECU yet. If you can locate your ECU, if it has 2 rounded edge connectors then it's the newer style ECU that we can support. If it uses the older single square edge connector then it is the older style ECU that we cannot support.

If you're in the Austin TX area, please join us for our dyno day event.

How much HP could I expect to get with UpRev tune, intake and exhaust?

The gains on an NA spec v aren't huge, maybe with some nice cams, matched with the right bolt ons you will see a decent gain. "Westner" on b15u.com hit 200whp in his built NA QR, and he still has some work to do, along with a retune.

On a boosted QR, this is your best bet though, no doubt.
